COLUMBIA, Mo. -

The University of Missouri has hired a Clayton-based law firm to conduct an investigation about the school's handling of the 2011 suicide of former swimmer Sasha Menu Courey.

Dowd Bennett Law Firm is scheduled to report its findings to the University of Missouri Board of Curators April 11.    The board announced Friday that none of the five lawyers working on the case are former employees or alumni.

University leaders say they didn't learn about a purported sexual assault against Menu Courey until she committed suicide 16 months later. They said they followed the law and didn't have specific knowledge of the incident or a victim to interview.

The case has since been referred to Columbia police.
